With the above and other objects in View, the invention. furtherincludes the following novel features and details of construction, to

be hereinafter more fully described, illus trated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings Figure 1 is an edge view of a cap constructed inaccordance with the invention.
